黑洞与热辐射的热平衡稳定性

THE STABILITY OF THERMAL EQUILIBRIUM BETWEEN A BLACK HOLE AND THERMAL RADIATION

对包含在一个刚性、绝热的盒子中的黑洞与热辐射的热平衡稳定性问题作了研究，得到一些有意义的结果：（１）Ｈａｗｋｉｎｓ稳定热平稳条件的等价表示；（２）对包含黑洞与热辐射的球形盒子半径Ｒ的限制；（３）黑洞与热辐射的动态热平衡满足广义热力学第二定律。

The stability of thermal equilibrium between a black hole and thermal radiation confined to a risid and adiabatic box is investigated in this paper.Some meaninsful results are obtained:(1)An equivalent expression for Hawking's condition of stable thermal equilibrium;(2)A restriction to the radius R of a spherical box enclosing a black hole and thermal radiation;(3)The dynamical thermal equilibrium between a black hole and thermal rad tat ion obeys the general lied second law of thermodynanlics.
